HRT after de 12 years?

[AlexUABC]

A while ago my uncle's shop entered a boy of 12 who did not know he was trans now he has breasts but according to the hormones should be taken after the 16 and with the permission of the parents but that made me remember stories where many women claim that many adolescents and girls secretly took estrogen drugs from their parents. (take the pills of breast, aunt or sister) without knowing the danger that many ran.
Were you one of them?

Back when I was a kid, those pills weren't commonly available and neither my mother nor sisters used them, though one sister should have.  However, given those pills came in blister packs, arranged on a schedule, a woman would have to be pretty dense to not notice some missing.
